The 5V USB power bank case converts one or more 18650 Li-Ion cells into a portable USB power bank the case handles voltage regulation, charge management and USB output, while the 18650 cells supply the raw energy storage. The aluminium body houses, the cells and the integrated charge and boost circuit that steps the 18650’s 3.7V nominal voltage up to the 5V USB standard that phones, Arduino boards and USB-powered electronics devices. Loading the case with 18650 cells and connecting Micro-USB for charging creates a functional power bank without buying a pre-built sealed unit the cells are user-replaceable when capacity degrades.
The 18650 power bank case charges through Micro-USB at 5V up to 1.5A and discharges through USB-A at up to 2A output.
